Be it known that We, THoMAs CHRISTIAN THOMSEN, subject of the King oftjweden` London, England, and ARTHUR A v' oi' England, at Lancashire,England, have innew and useful Improvements in Force-Feed Lubricators,or" which thejollowing is a specification.

This invention relates to improvements in force feed lubricators,oneobject being to provide a lubricator 'n which each pump and itsoperating mechanism is immersed 1n oil,l and the. valve bon is situatedwithout the oil casing so as to permit of ready inspection andcleaningof the valves or" each pump.

@ther objects are to provide means by which the'plunger of each pump canbe operated by hand inc lependently of the mainv operating mechanism,and means by which the stroke of each plunger can be readily roperation, said band and stroke adjusting' means without the oil casingnormally reciprocated of the pump barrel by being operable from e pumpplunger is over a certain stretch the operating mechanism Within theing, but when a sudden excess orfilush ot oil is required the plunger isadapted to be reciprocated by hand over a different and preferablylonger stretch of the pump barrel. By this means, and in vieuY of thehand operating meansfbeing independent of the normal operatingmechanism, the stroke adjusting means need not be interfered with afterit- .hes ence been set accurately to suit casing near the bottom thereofso that the barrels are immersed in oil.

barrel is provided with a valve box which block e, integral with each`barrel, the block being oil eas-4 hole 1n one side of the tended Dee, l1%.?, serial no. assess.

bored so as to form a suction passage d, and a delivery passage e. Eachblock' c, is fitted against the outer surface of one side ,of the oilcasing a, being secured by suitable means such as screws j". The suctionanddelivery passages are provided with suitable valves such as ballvalves, It is preferred to use two suction valves 57, it, and twodeliver valves z', la. The valves g. la., are preferably mounted in aplug Z, which is'screu'ed into the suction in aliiieinent soA that Whenlthe plug Z. is rev moved both passages can be clearerlbyimeans of a wireor the like. f he suction passage rl, communicates with the oil casinga, by means of a lateral pas sage m, formed partly in the block 0, andpartly djeocnt side of t e easing. The delivery valve fr, is preferablyheld to its seat during the suction stroke bye spring n, which maybearranged conveniently with# in a nozzle o. A plunger g2, is lifted ineach pump barrel and has a head Q, against which one end of a spring77,' abuts, l The head g, preferably has a hardened steel face s,against which suitable operating mechanism Works to force in the plungeron the delivery stroke, the plunger eine; moved in the oppositedirection'hy the spring r. The operating mechanism may be of anysuitable kind such as an oscillating arm t, fitted with an impact ballu. the 'erm if, mounted on a shaft v, oscillated by a lever 'w as usualin force feed lubricetors, The shaftI 0, maybe retated as in some knownforms of lubricator in which ease is provided with a cern (Fig. 3) thecam being preferably grooved' and fitted with e loose ring y. in oneform the plunger go, has an extenj sion e, passingthrough the valve bonwhich f is provided with a packed glandQ (Fig. l), I the extension a,having a handle 3, on its end.

i. lock nut 6, is preferably provided to vent the nut 5, movingaccidentally. The handle 3, permits of hand operation of the plunger 0,independently of the main operpre- Cfr
